S PECTACLE ATTACHIVI ENT.

SPECIFICATION forming part of Letters Patent No. 671,051. dated April 2,1901.

Application filed August 80,1900. Serial No. 28,493. (No model.)

To all whom, it may concern:

Be it known that I, WARREN O. JONES, a citizen of the United States,residing in the city and county of San Francisco, in the State ofCalifornia, have invented certain new and useful Improvements inSpectacle Attachments; and I do hereby declare the following to be afull, clear, and exact description of the same. 7

The invention relates to'that class of spectacles commonly known aseyeglasses, and more particularly to an improved pad or cushion by meansof which the glasses are firmly secured to the nose and prevented fromfalling off during movement of the wearer or from slipping or turningover by reason pf perspiration. It is a well-known fact that spectaclesof this class are difficult to maintain in proper position and ofttimes,owing to the shape of the nose, cannot be used at all, due to the factthat the cushion cannot obtain sufficient hold to secure the glasses.The cork, composition, and metal pads or cushions at present employed donot prevent the glasses slipping, turning, or falling off, especiallyduring warm weather, when the wearer perspires freely.

The object of the present invention is to dispense with the cushions orpads at present employed and to provide a cushion, pad, or cushioncovering by means of which the glasses may be maintained in properposition and prevented from dropping off or slipping upon the nose.

In order to understand the invention, reference should be had to theaccompanying sheet of drawings, wherein- Figure 1 is a perspective viewof the glasses with the improved cushion or pad attached thereto. Fig. 2is an enlarged detail plan view of the pad or cushion, and Fig. 3 is aside edge view thereof.

In the drawings the letter A indicates the spring cushion-plates. Theseplates are generally provided with a cork, leather, or compositioncushion or pad, which cushion or pad in many cases is roughened, so asto secure a hold upon the nose. Such form of cushions or pads do not,however, answer to-hold the glasses firmly in place and prevent theturning or slipping thereof, especially during hot weather.

My improved cushion or pad consists of sharks skin. This skin isprovided on the surface with small rough elevations, or rather thescales are small and provided with radiating curved points, known asosseous tubercles. The skin thus presents a tooth-like surface, theteeth of which slightly incline. This will be understood by reference toFigs. 2 and 3 of the drawings, wherein the numeral 1 represents the skinproper, 2 the scales, and 3 the radiating curved points. The skin is sosecured to the cushion-plates that the points 3 upwardly incline orpitch.

In Fig. l of the drawings I have illustrated the most common form ofeyeglasses; but it will be understood that the cushion or pad may bereadily attached to any style of glasses or cushion-plates.

I have ascertained from practical use that the described pad or cushionfirmly secures and maintains the glasses in proper position upon thenose. While the projecting points 3 bite,so to speak, into the flesh ofthe nose a sufficient depth to hold the glasses, still, owing to thesmallness thereof, they do not tear or injure the same in any waywhatever.

Inasmuch as the projecting points 3 form a series of air spaces orpassages for the circulation of air burning or undue heating of theflesh is obviated.

The length of the skin cushion or pad is im* material, as it mayentireiycover the cushionplates or only a portion thereof. Owing to thebony nature or character of the skin the same is not affected bymoisture or perspiration.

Having thus described the invention, what I claim as new, and desire tosecure protection in by Letters Patent, is

1. As an article of manufacture, a nosepiece for eyeglasses having agripping-surface provided with a multitude of upwardly-in clined pointedprojections arranged throughout the same, substantially as described.

2. As an article of manufacture, a nosepiece for eyeglasses havingagripping-surface made of sharks skin provided with a multitude of upwardlyinclined pointed'projections arranged throughout the same,substantially as described.

In witness whereof I have hereunto set my hand.
